- SND_PCI_QUIRK(0x1025, 0x006c, "Acer Aspire 9810", ALC883_ACER_ASPIRE),

seem same pci ssid

- [ALC883_ACER_ASPIRE] = {
- .mixers = { alc883_acer_aspire_mixer },
- .init_verbs = { alc883_init_verbs, alc883_acer_eapd_verbs },
- .num_dacs = ARRAY_SIZE(alc883_dac_nids),
- .dac_nids = alc883_dac_nids,
- .dig_out_nid = ALC883_DIGOUT_NID,
- .num_channel_mode = ARRAY_SIZE(alc883_3ST_2ch_modes),
- .channel_mode = alc883_3ST_2ch_modes,
- .input_mux = &alc883_capture_source,
- .unsol_event = alc_sku_unsol_event,
- .setup = alc883_acer_aspire_setup,
- .init_hook = alc_hp_automute,

does the notebook has subwoofer ?

-/* toggle speaker-output according to the hp-jack state */
-static void alc883_acer_aspire_setup(struct hda_codec *codec)
-{
- struct alc_spec *spec = codec->spec;
-
- spec->autocfg.hp_pins[0] = 0x14;
- spec->autocfg.speaker_pins[0] = 0x15;
- spec->autocfg.speaker_pins[1] = 0x16;
- alc_simple_setup_automute(spec, ALC_AUTOMUTE_AMP);
